Prado and installing PHPExcel - Auto Loading bug

Well this was a headache and then some.

The problem is Prado has a Auto Loading process that can cause 3rd party or additional libraries to break and act strange if they also have a Auto Loading process.

The Solution is to turn off Prado's Auto Loading process, Load the 3rd party/Additional library and then turn Prado's Auto Loading process back on.

Here is what it looks like: (In this example I'm using the namespace instead of the path alias)

$phpExcelPath = Prado::getPathOfNamespace('Application.Core.php_excel.Classes');

// Disable Prado Auto Loading process

// Add PHP Excel

// Do PHP Excel stuff here

// Reload Prado Auto Loading process

They are using YII but the process is very similar

There is a discussion here for possibly more information regarding this issue.
